In the updated HW-wrapped key code in the android14 kernels, HW-wrapped
keys are only allowed on a multi-block-device filesystem if they have a
compatible HW-wrapped keys implementation. While in principle this is a
good thing to check, my implementation of it, which simply checks
whether the block devices have the same crypto profiles, doesn't work
when device-mapper is being used.
To actually do that check correctly, I think we'd need to add a
HW-wrapped keys implementation name or ID to the crypto capabilities.
That being said, in Android the HW-wrapped keys implementation is a
global thing anyway. So in the interest of not overcomplicating things,
for now let's just drop these extra checks that are causing problems.
